Macbook pro 16 + eGPU = Any heating issues?

I am considering of picking up the new macbook pro and an eGPU so i can play AAA games. I am just curious for those who have been gaming with a similar setup has heating been an issue? im weary that overheating will degrade the computer in the long run.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Intel processors are designed to run hot.

You’ll have to wait for an ARM-based model if that’s not going to work for you.

@kingstada, Apple allows their cpu's to run hot under load, usually brushing up against the throttling temperature, even in MacOS.  In bootcamp they set the pl1 and pl2 values to 125w and basically allow the cpu to perpetually sawtooth to 100 degrees c and some lower temp as it throttles then unthrottles repeatedly.  You can use programs like throttlestop and XTU to set the max power limits lower, but I found that I had to take them down to 45w to keep [email protected] stable at around 90 degrees c.  Performance in benchmarks like cinebench r20 were better with the default behavior than with a TDP limit in place.  In MacOS there is mostlikely factory underclocking and extensive performance optimization by the SMC in the t2 chip, and it can sustain 60-70w under most full load scenarios while staying around 90 c sustained with little fluctuation.  Gaming workloads will be less than this typically but still generate a lot of heat.
